Aggregate mining is one of the most important activities in the supply of materials to the construction industry. Sand is one of these materials. This sand can be extracted from different places, but extraction is mainly carried out in riverbeds and sand dunes. The detrimental effects of human activity have been recorded in dune environments. Different activities such as urbanization, vehicle traction or mining, account for erosive or degradation effects on the integrity of these environments. In Argentina, since the middle of the 20th century, the continuous growth of coastal urbanizations has demanded that the supply of sand be continuous for the area, in order to maintain urban development. In the case of the Atlantic coast, the sand used in construction comes from the coastal dunes located in the eastern dune barrier. This generates a local disturbance, the extent of which is not estimated. Currently in the aforementioned barrier, there is only one legal sand mining company that performs sand mining. Therefore, to evaluate the level of environmental disturbance in the area, a bioindicator was used. The species Ctenomys talarum has a great association with the dunes, because it is a semi-fossorial organism that develops in sandy environments. The characteristics of its life cycle make it an ideal bioindicator to establish the degree of disturbance in the area. To carry out this evaluation, different biotic and abiotic factors were measured, as well as the distribution of individuals in the area, using the location of their burrows as a proxy. For this, 4 sectors corresponding to exploitation areas were measured, plus an area of interduna left as conservation. The results showed that the main limiting effect on the development of the tuco-tuco populations in the area is due to the fact that, due to the depressions corresponding to the extraction of sand, they generate puddles in the rainy season, so that the area is reduced. employment potential for tuco-tuco individuals. Abiotic factors remain unchanged in general terms, however, biotic factors seem to accompany the hydric dynamics of the area. The situation is reversed in the conservation area, the ponding is reduced compared to the exploited areas, increasing the occupation area for individuals. In this way, the transit dynamics of the tuco-tuco could be from the conservation zone out through the connectors that remain in the exploited areas, and vice versa, so the dynamics within the area could not stop. Future studies will complete these results.
